Chromosome fragmentation vectors (CFVs) are used to create deletion derivatives of large fragments of human DNA cloned as yeast artificial chromosomes (YACs). CFVs target insertion of a telomere sequence into the YAC via homologous recombination with Alu repetitive elements. This event results in the loss of all YAC sequences distal to the site of integration. A new series of CFVs has been developed. These vectors target fragmentation to both Alu and LINE human repetitive DNA elements. Recovery of deletion derivatives is ten- to 20-fold more efficient with the new vectors than with those described previously.
